    摘要： The invention relates to the use of at least one compound comprising at least two hydroxyl functions, the compound being selected from alcohols, aminoalcohols, carboxylic acids and hydroxyacids, for preventing the crystallization of boric acid present in an aqueous phase, or for suppressing this crystallization when this crystallization has already been initiated.Applications: fields in which boric acid may be used and, in particular, those in which it is necessary to rapidly have available aqueous phases containing a high concentration of boric acid which do not include boric acid crystals, for example in the nuclear industry.

    摘要： Methods of synthesis of scyllitol diborate and related compounds are provided, including methods that are performed in all-aqueous solutions. Also provided are methods in which the reaction products are recycled to increase the efficiency of the process. The methods include the steps of conversion of a solution of inositol to scyllitol, conversion of scyllitol in the solution to scyllitol diborate, and isolation of the scyllitol diborate from the solution. The scyllitol diborate is reacted to form substantially pure scyllitol diborate, and the remaining solution is efficiently recycled to scyllitol diborate, then to additional substantially pure scyllitol. This scyllitol diborate recycling step can be applied to a variety of processes to improve the yield of scyllitol. The methods are highly efficient and result in large scale reaction products of high purity.
